Rank the following velocities according to the kinetic energy a particle will have with each velocity, greatest first: (a)

To rank:
The velocity according to the greatest kinetic energy at first.
Answer to Problem 1Q
Solution:
All velocities have the same kinetic energy.
Explanation of Solution
1) Concept:
To rank kinetic energy, we have to find first find the resultant velocity, and then use the formula for kinetic energy in which the mass is the same for all velocities. Therefore, kinetic energy is ranked only on the magnitude of velocity.
2) Formula:
i)
ii)
3) Given:
i)
ii)
iii)
iv)
v)
vi)
4) Calculation:
First find the resultant velocity as follows:
For
For
For
For
For
For
Now kinetic energy can be found by using the following formula:
Assume
So
As the resultant velocity
Conclusion:
Resultant velocity is found by using Pythagoras theorem; from where the kinetic energy could be calculated.

- Hi! I need help with these calculations for part i and part k for a physics Diffraction Lab. We used a slit width 0.4 mm to measure our pattern.arrow_forwardExamine the data and % error values in Data Table 3 where the angular displacement of the simple pendulum decreased but the mass of the pendulum bob and the length of the pendulum remained constant. Describe whether or not your data shows that the period of the pendulum depends on the angular displacement of the pendulum bob, to within a reasonable percent error.arrow_forwardIn addition to the anyalysis of the graph, show mathematically that the slope of that line is 2π/√g . Using the slope of your line calculate the value of g and compare it to 9.8.arrow_forward
- An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?arrow_forwardConcept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem. The distance between an object and its image formed by a diverging lens is 5.90 cm. The focal length of the lens is -2.60 cm. Find (a) the image distance and (b) the object distance.arrow_forwardPls help ASAParrow_forward
